selected-listener-pane

Arguments: &key no-create

Returns the currently-selected IDE listener pane. It may be desirable
to print debugging output to this particular stream, though IDE
Listener processes and processes started by Run | Run
Project generally handle that for you by binding the standard
output streams to the selected listener pane.

If no-create is nil (as it is by default) and no IDE Listener exists,
then one will be created. If true, then a listener is never created
by calling this function. This argument is probably not useful to
users since there normally is always at least one IDE Listener in the
IDE.
